Single 0, or 2AWG wire pricing (slightly OT)

I'm looking to have a 15kW natural gas generator installed. I have two choices, since my NG meter and electricity meter are on opposite sides of the house (about 250 zig-zag ft away). I talked with a few plumbers about burying NG pipe to feed the generator and that bill was $2500.



Option B is to put the genny close to the NG and run heavy wire to the fuse box. before I talk with the electronical guys I'd like to get an estimate of how much the wire is going to cost.



I'm assuming for a 250' run I'll need at least 800' for the three wires (hot1 hot2 and neutral).



Does it need to be in conduit since it will be running through my attic and breezeway?



Where can I find a supply shop that carries this type of wire?

A lot. Copper is pricey these days.

Maybe, depends on code. Might also be combined in a single plastic jacket. I don't think lone wires, even bundled together, are ever allowed anymore, why I don't know. At any rate, the conduit is probably 1.5" or so (again, check code), which isn't too expensive, being a steel product.

Anywhere that supplies building supplies. Phone book under "electrical supply", Home Despot (not sure if they have 0AWG), etc.

About that 0AWG: 15kW at 240V is about 60A, which is rated for 6AWG about.

4AWG would be more than enough, even over the long run you have to cover.

He may be thinking of aluminum cable, which is often used for the big runs, as it's less expensive - but needs to be at least one size larger.

Had not really thought of that but it is a good idea. I'll have to look at the terminations on either side to make sure they will allow aluminum wire instead of copper.
